Structure and dynamics of silver fir (Abies alba Mill.) population in forest communities of the Świętokrzyski National Park. II. Population dynamics

Maria Mazur

Abstract


The paper presents the dynamics of silver fir population, and forecasts the changes in its size. The studies were conducted within the area of fir decline, in a fir forest and Carpathian beechwood. Changes in the size of following groups were illustrated in diagrammatic life-tables: i.e. seedlings, new growth, up-growth, and trees. The direction and rate of expected changes in the population was inferred from the matrix model. The studies showed that the population was in a regression phase. Population growth rate λ amounted to 0.83.
